Been experiencing random hardware lockups whilst trying to play Oblivion with my Radeon X1900GT. Seems to kick in shortly after leaving combat then for no apparent reason the framerate drops, a 1pixel tall line flashes across the top of the screen then the sound produces an EMI "static". Using: Catalyst 6.12 (Non-chuck patch) Default clock speeds Latest UK patch for Oblivion (1.1). Problem is only present in Oblivion, none of my other games have this issue (FEAR, Farcry, WoW, WC3, Morrowind, NWN2, HL2, Flatout, Doom 3, Painkiller, UT2004). Tried a fresh install of game, Catalyst drivers (with driver cleaner), default settings for CPU/System, fully patched WinXP Pro SP2, latest build DX9 etc. I am using the latest Creative drivers (22nd Dec I think) incase it might be a sound related issue. Anyone else experienced similar issues, have a solution for this or am I just really unfortunate? AFAIR, the demo worked fine.
